Species
Taxon distribution as listed in assessment
In the UAE, this species is restricted to the southern Hajar Mountains, from the Fujairah area (G.R. Feulner in lit. in MEW 2010) and the 'Olive Highlands' to Jebel Hafeet (M. Jongbloed in Jongbloed et al. 2003, Feulner 2014). The species occurs in Wadi Helo (El-Keblawy et al. 2016), and has been recorded from Jabal Sahab, olive wadi (Wadi Sfai; M. Tsaliki pers. comm. 2019). This species is endemic to the Arabian Peninsula, where it is found from eastern central Yemen to Oman (Board of Trustees, RBG Kew 2019) and the eastern UAE.

Assessment rationale/justification
In the UAE, this species is restricted to the southern Hajar Mountains and to Jebel Hafeet. The extent of occurrence (EOO) is restricted, and the area of occupancy (AOO) is also likely to be highly restricted given the scattered distribution. The species occurs in more than ten locations, including protected areas, however the population size is inferred to be low, likely to be less than 1,000 mature individuals. As a result, the species qualifies as Vulnerable (D1). Whilst the species occurs in Oman, the potential for any rescue effect is not known, and no regional adjustment is applied.
